After 12 years of being shelved, Midnight Sun has finally been released.

Midnight Sun, a retelling of Stephenie Meyer’s first Twilight story from the perspective of Bella’s vampiric love interest Edward, has sold more than one million copies in all formats in the United States since it was released on August 4. In the UK, 62,460 hardback copies of the book were sold in just three days. The success of the book’s release placed Meyer at No. 1 on the Nielsen BookScan’s charts.

Now, Meyer has revealed she has plans for at least two more books, which are set to be part of her vampire saga Twilight. On Monday, during an online event with Books-A-Million, Meyer said, “There are two more books I think in the world that I want to write. I have got them outlined and a chapter written I think of the first one, so I know it’s there. I am not ready to do that right now, I want to do something brand new.”

Meyer first announced the publication of Midnight Sun in May, 12 years after she abandoned the manuscript due to an online leak of a draft. Meyer called the leak “a huge violation of my rights as an author, not to mention me as a human being” and halted the project indefinitely. In 2013, the author said that she would never write another Twilight book. In an interview with Variety, Meyer said that she would only do so if it was “three paragraphs on my blog saying which of the characters died.”

The first four books in the Twilight series were published between 2005 and 2008 and have sold more than 100 million copies worldwide. The books inspired a five-film adaptation, which raked in $3.3 billion. The films starred Robert Pattinson, Kristen Stewart, and Taylor Lautner.
